Definitions
- the present invention relates to a formulation and a method of coating at least one water-based binder and / or on a ceramic material based flat plate element According to the preamble of claim 1, a use of Formulation or method and a Fiber cement board, coated by means of a formulation respectively. a procedure.
- Fiber cement boards may vary depending on the environmental conditions, such as temperature, humidity, etc., deform. So can For example, attached to a facade Fiber cement boards deform such that both so-called bowl (lowering the front opposite Zero line of the undeformed plate), as well as a crowning (Lifting the front opposite the zero line of the undeformed plate) may occur. The result of this is uneven wall surfaces showing the appearance of the Strongly affect the facade.
- such plates at least coated on one side to prevent deformation.
- a plate having a water-based Binder and / or based on a ceramic Material, in particular fiber cement boards or Clay plates, equip such that the aforementioned required properties can be achieved.
- a coating wherein a formulation is used for the coating, consisting of at least two dispersions, one of which Dispersion film-forming and blocking resistance has guaranteeing properties and the other Contains dispersion components with functional groups, which are suitable for after application of the coating a chemical reaction with components in optionally other coatings, such as the above-mentioned adhesive or with so-called primers.
- the blocking resistance of the coating can be increased thereby.
- the other dispersion preferably has components reactive groups which are suitable, a good one Adhesion to adhesives, such as 1K-PUR building adhesives, to enable. It is accordingly advantageous when the reactive groups of the components in the dispersion are suitable for reaction with isocyanate groups, which in the mentioned 1K-PUR building adhesives available.
- the dispersions are advantageously aqueous Dispersions based on acrylic polymer, wherein the polymers self-crosslinking.
- aqueous dispersion based on acrylate-styrene polymer or the use of an epoxy-functionalized Acrylate is proposed.
- aqueous polymer dispersions such as dispersions based on Polyurethane, silicone, epoxy, etc., such as Silicone-acrylate dispersions.
- dispersions film-forming additives and / or adhesion-improving additives as well as defoamer.
- an aqueous Acrylate dispersion comprising components with reactive Groups such as HO, thiol, amino, epoxy and / or Episulfide.
- aqueous Dispersions For application, first the two aqueous Dispersions in a mixing vessel by means of a Mixing unit, such as a dissolver, so mixed together, that one at least nearly homogeneous Mixture arises. Subsequently, the mixture of two aqueous dispersions by means of casting, spraying, using calender, etc., on one side of the plate applied.
- a Mixing unit such as a dissolver
- the methods defined according to the invention are especially suitable for coating or finishing of fiber cement boards.
- the further dispersion Setalux 8551 AQ-45 is an epoxy-functionalized dispersion which is normally used as one of two components in a two component epoxy-amine curing dispersion. It has a solids content of 43-46%, a density [g / CM 3 ] of 1.05, a flash point> 65 ° C and an epoxy equivalent weight, based on the solids content of 621.
- dispersions may contain further additives, Contain additives or adjuvants, such as Pigments, dyes, emulsifiers, pigment dispersing additives, Wetting and surface additives, Antioxidants, settling additives, heat stabilizers, UV absorbers and fillers, catalysts, etc.
- Contain additives or adjuvants such as Pigments, dyes, emulsifiers, pigment dispersing additives, Wetting and surface additives, Antioxidants, settling additives, heat stabilizers, UV absorbers and fillers, catalysts, etc.
- the epoxy-functionalized dispersion Setalux 8551 AQ-45 represents a significant improvement in liability and another improvement in the crowning and Bowl behavior safe.
- the isocyanate group-containing prepolymers for example a 1K PUR adhesive, which is usually used for attaching fiber cement boards to a substructure consisting of aluminum or wood in buildings, react after application of the adhesive with the air moisture with elimination of CO 2 to a amino group.
- This can on the one hand react with an isocyanate group of another prepolymer in the adhesive to form a urea, which leads to crosslinking of the adhesive.
- this amino group is available at the interface for reaction with corresponding chemically reactive groups.
- Such a group can be an epoxy function, as in the mentioned dispersion of Setalux 8551 AQ-45, which undergoes an addition reaction with the amino group and, via the newly formed bond, ensures the adhesion of the dispersion coating on the fiber cement board to the adhesive.
- a primer is applied between the adhesive and the backcoat, which itself may be both isocyanate-free and isocyanate-containing.
- any solvents and / or plasticizers which are usually contained in an adhesive can dissolve or soften the not yet fully crosslinked primer and thus come into contact with the adhesion-friendly backside coating.
- Experiments with and / or without primers show in both cases a significant improvement in adhesion, which is due to the epoxy functionalities in the dispersion used according to the invention.
- fiber cement panels became one Formulation with the designation GT93 applied, merely containing the dispersion labeled Setalux 6755 AQ-40, thus improving the stabilization of the Plate can be achieved, as well as an improvement of Blocking resistance.
- Peeltests peel test
- it shows a significant poorer adhesion to the construction adhesive mentioned and so-called Peeltests ( peel test) for checking the Adhesion of the adhesive on the backside coating revealed that the break was largely along the Interface between adhesive and coating was.
- peel test or peel test resulted Use of the dispersion combined according to the invention, that the adhesive breaks in (cohesively) so on the Backside coating remains.
- an improvement with both use of a Primer or without using a primer is achieved.
- Figure 1 shows pendulum hardness king (s) at a Wet film thickness of 200 ⁇ m, knife lift and drying for 20 minutes at 80 ° C.
